FLAT-1R0 N.

SPECIFICATION forming part of Letters Patent No. 423,376, dated March 11, 1890.

Application filed February 18, 1388. Serial No. 264,535. (No model.)

In the drawings, forming part of this speci-' fication, Figure l isa side View of the flatiron. Fig. 2 is acentral longitudinal vertical section of Fig. 1. Figs. 3 and 5 are perspec ti ve views in detail, as will hereinafter appear. Fig.4 is a transverse vertical section on line 4 4, Fig. 2.

In the drawings, A is the body of the flat iron of this invention, and this body has a bottom B, provided exteriorly with a smoothing or ironing surface 0 and sides D D, front and rear ends -E E and a top F, the whole making an inclosed chamber G, having air and gas communications, all substantially as well known and otherwise in accordance with this invention, as hereinafter particularly explained.

His the handle suitably secured to the top F, and the top is made separatefrom the sides and ends of the flat-iron and secured thereto by screws J, entered through it and screwing into the side walls, two screws on each side. Again the top has a chamber K on its under side extending along its width and length and lying above the chamber G of the flat-iron. This chamber K is closed on all sides, and is filled with asbestus L, or other suitable nonconductor of heat, which prevents the conduction of heat through the top of the fiatiron to the hand of the user. The bottom plate M of this asbestus-filled chamber K of the top F is detachably attached-as, for instance, by means of screws, (not shown,) so that it may be readily removed.

N is a nipple screwed into and through the central part of the base-plate O of the handle II, and projected into an inclosed chamberP of the top, having holes a for the admission of air thereto. The base-plate O is open on its opposite sides (see Figs. 1, 2, and 4) and on and against the nipple at its opposite sides and passing over the top of the elbow-fitting R, (see Figs. 1, 2, and 3;) but the elbow-fitting may be confined on the nipple in any other well-known way, the way particularly described forming no part of this invention. The air-mixin g chamber is at the central part of the asbestus-filled chamber K, but closed therefrom, and it bears on the detachable plateM of said chamber, and the bearing is packed with asbestus, as at T, or other suitable non-conductor of heat and its so-bearing portions. Said asbestus packing and said detachable plate M have a coincident passageUthrough them continued with a tube V, preferably integral with said plate. This tube V at its lower end communicates with a block-tip W, resting on the inside of the bottom of the iron, and having opposite projecting arms X in the direction of the length of the iron, and each of which has an opening Y, elongated in the direction of the width of the bottom. The gas from the gas-supply passes first into and through the gas and air mixing chamber P, and thence into the tube V and out through the openings Y. This block-tip WV is within a horizontal chamber Y at and along the bottom of the flat-iron, and having an archshaped top Z of nearly the full width of and resting on the bottom of the fiat-iron. This arch-shaped top Z extends partially along the length of the bottom, and the chamber made by it at each end is open to the inclosed chamber G of the fiat-iron as also at the top through an opening A in its central portion.

B B are apertures in the side walls of the flat-iron for the admission of air to its inclosed chamber G, and C G are apertures at each end of' the top, also making commhnication with said inclosed chamber.

In the fiat-iron described the gas supplied is mixed with air in the gas and air mixing chamber P, and thence passes and is consumed at the elongated openings Y of the tip-block, which, acting in conjunction with the arched top, spreads its flames over the inner surface of the bottom of the iron, the vapors therefrom escaping at the open ends of said arched top Z.

As the combustion above stated goes on, the air passing in through the openings in the sides of the fiat-iron furnishes a draft of air through the openings A of the arched top to the gas-burning chamber thereunder, which increases the attenuation of the gasfiames and gives increased action thereto on the inner surface of the bottom of the iron to heat the same.

The tube V, leading from the gas and air mixing chamber P to the gasburning chamber Y has side wings D Fig. 5, the ends E of which abut against the top of the arched top of said chamber, andwhen the flat-iron top F is attached by the screws J, as has been described, said arched top is consequently bound and held firm against thebottom of the flat-iron, and all parts of the iron body are thus made fast and firm-plainly a most 4 simple and efficient construction and arrangeinent.

The air-ports a of the air and gas mixing chamber P are regulated in size and opened and closed by means of a rotating registerplate G having corresponding ports suitably applied for that purpose and which constitutes no part of this invention.

through the top of the iron practically reduced to the minimum.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. The combination, with a flat-iron body having a chamber G, with openings 13 on its opposite sides, of a handle H, having a central base O,with side openings and secured to central portion of fiat-iron top F, an inclosed chamber P at central portion of said top F,

ber P and side openings of said handle-base O, a tubular nipple N, open 'at its opposite ends and passed through and held in handle chamber Y and having elongated openings Y on it-sopposite sides and toward the opposite ,open ends of chamber Y as described, for the purpose specified.

2. The combination, with a flat-iron body A, having a chamber G, with openings B on its opposite sides, of a removable top F for body A, screws J attaching top to body A, a chamber Y within said chamber G and along and lengthwise of'the bottom of the fiat-iron, an arched top Z for said chamber Y open at its opposite ends, a gas-tube V, held by and entered through the flat-iron top F, the tube V passing through said arched top Z into chamber Y and wings D on opposite sides of tube V bearing upon said arched'top, substantially as described, for the purpose specified. 4

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
